Detailed Description
The following description and the annexed drawings set forth in detail certain illustrative embodiments of the application so as to enable those skilled in the art to practice them. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The scope of the embodiments of the present application includes the full ambit of the claims, as well as all available equivalents of the claims. Embodiments may be referred to herein, individually or collectively, by the term "invention" merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed. Herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed. The embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. For the structures, products and the like disclosed by the embodiments, the description is relatively simple because the structures, the products and the like correspond to the parts disclosed by the embodiments, and the relevant parts can be just described by referring to the method part.
The network structure of the IAB is shown in fig. 1, in the IAB network, each node supporting wireless backhaul is called an IAB node, the IAB node supports the function of a gNB-DU, which is called an IAB-DU (Distributed Unit), and the IAB-DU can serve a general UE (User Equipment) and an IAB child node. The IAB node also supports part of the UE functions, which may be referred to as IAB-MT (MT, mobile Terminal). The IAB-MT may support functions such AS UE physical layer, AS layer, RRC and NAS layer, and may be connected to an IAB parent node. The terminating node on the network side is called an IAB-donor, that is, a donor base station, and provides network access for the IAB-MT or the UE through a backhaul or access link. The IAB-donor can be further divided into an IAB-donor-CU (Central Unit) and an IAB-donor-DU, wherein the IAB-donor-CU and the IAB-donor-DU are connected through a wired network.
In addition, the relationship of the IAB nodes is shown in fig. 2. The last hop neighbor node of the IAB-MT is called the parent node, which may be the IAB node or IAB-donor. The next hop neighbor node of the IAB-DU is called a child node, and the child node is another IAB node. The direction to the parent node is referred to as the upstream direction, and the direction to the child node is the downstream direction.
According to the specification of 3gpp R16, the primary IAB features are designed based on the assumption that all IAB nodes are statically deployed. For stationary IAB nodes, since the distribution of cells is fixed, the upstream and downstream node relationships and channel conditions of the backhaul link are relatively stable. With the development of the technology, the support for mobility of the IAB node is introduced into the research topic, and when the IAB node moves, due to the influence of the displacement, the re-establishment of the backhaul link and the access link may be caused. In the upstream direction, the IAB-MT of the IAB node may lose the connection with the original parent node and seek a new parent node to establish the connection. In the downstream direction, the IAB-DU signal of the IAB node may lose the connection with the UE or sub-node in the original coverage area, and the UE or sub-node in the new coverage area may establish a new connection with the IAB-DU of the IAB node. However, if the IAB-MT performs cell selection in the role of UE or the IAB network selects a handover target cell for the IAB-MT according to the basic protocol, the relative strength of the cell signal of the parent node can only be considered generally, but if the knowledge of the mobility characteristics of the parent node is lacked, it is easy to establish an unstable backhaul link.
In order to solve the above problem, an embodiment of the present invention provides a node access method. As shown in fig. 3, fig. 3 is a flowchart of a node access method according to an embodiment of the present invention. The node access method provided by the embodiment of the present invention may be executed by a node access device, where the node access device may be implemented in a software and/or hardware manner, and the node access device may be formed by two or more physical entities, or may be formed by one physical entity. The node access device may be a base station, for example. The method comprises the following steps:
In this embodiment, after each IAB node in the IAB network is started, system information broadcast by each candidate parent node is detected, where the system information broadcast by the candidate parent node includes a backhaul hierarchy of the candidate parent node. The backhaul level is used to indicate how many routes the node reaches the IAB-donor-DU of the donor base station through, where the backhaul level corresponding to the IAB-donor-DU of the donor base station should be 0, the backhaul level corresponding to the IAB-donor-DU of the donor base station should be 1, and so on, which are not described in this embodiment. In addition, the backhaul level of the IAB node may be determined by the routing configuration.
In this embodiment, each IAB node corresponds to at least one candidate parent node, and each candidate parent node corresponds to at least one candidate cell, as shown in fig. 4. After receiving the system information broadcast by each candidate father node, the mobile deployment type IAB node can determine the return hierarchy of each candidate father node according to the system information, so that the target cell can be selected based on the mobile attribute of the IAB node and the return hierarchy of each candidate father node.
On the basis of the above embodiment, each candidate parent node corresponds to at least one backhaul level, and each candidate parent node publishes its backhaul level following the same rule when broadcasting system information, where the rule includes: the backhaul level with the smallest priority is selected for publication, the backhaul level with the largest priority is selected for publication, or the backhaul level with the highest frequency of use is selected for publication.
It should be further noted that, in this embodiment, since the IAB network supports a topology architecture towards an acyclic graph (DAG), one IAB node may return through more than one parent node, and different return paths may cause the same parent node to have different return levels. Therefore, in this embodiment, when broadcasting system information, a parent node in the IAB network needs to publish its backhaul level according to the same rule, where the rule includes: preferentially selecting a smaller backhaul level for publication; preferentially selecting a larger return hierarchy for publishing; the backhaul level with higher usage frequency is preferably selected for publication. The IAB network may optionally publish a rule on the backhaul level of the parent node.
And 102, when the mobile attribute of the mobile node is determined to be a mobile deployment type, performing wireless measurement on the candidate cell corresponding to each candidate father node to obtain a wireless measurement index of each candidate cell.
In this embodiment, each IAB node is pre-configured with mobility attributes. The mobile attribute includes a fixed deployment type and a mobile deployment type, which are respectively used to identify whether a wireless cell corresponding to an IAB base station of the IAB node is in a fixed deployment or a mobile deployment, and whether the IAB node moves is determined by an installation scenario of the IAB base station itself (e.g., whether the IAB base station is installed in a house or on a car). For an IAB-DU, the mobility attributes may be fixed deployment type or mobile deployment type, and for an IAB-donor-DU, the mobility attributes should be fixed deployment type. After each IAB node determines its own mobility attribute, for an IAB node whose mobility attribute is a fixed deployment type, if there are multiple candidate parent nodes, the IAB node whose mobility attribute is the same as the fixed deployment type should be preferentially selected as the parent node (the mobility attribute of the parent node may be broadcast in the system information) when the S criterion is satisfied, thereby avoiding the occurrence of unstable backhaul link caused by selecting the parent node of the mobile deployment type. For a specific process of accessing the IAB node of the fixed deployment type to the parent node of the fixed deployment type, reference may be made to the prior art, which is not described in detail in this embodiment.
For an IAB node with a mobile attribute of a mobile deployment type, since the mobile attribute of its parent node is not necessarily able to ensure long-term stability of a backhaul link, no matter whether the mobile attribute is of a mobile deployment type or a fixed deployment type, there is no limitation on selecting the mobile attribute of the parent node. For an IAB node with a mobile attribute of a mobile deployment type, if a plurality of candidate father nodes exist, the optimal target cell is screened out for access on the basis of the signal strength of the candidate cell corresponding to each candidate father node. Therefore, in this embodiment, the IAB-MT of the IAB node requiring mobile deployment type performs wireless measurement on the candidate cells corresponding to each candidate parent node, so as to obtain a wireless measurement index of each candidate cell, where the wireless measurement index can reflect the signal strength of each candidate cell. In one embodiment, the wireless measurement metrics include: any one of reference signal received energy RSRP, reference signal received quality RSRQ, and signal to interference and noise ratio SINR. Reference Signal Receiving energy RSRP (Reference Signal Receiving Power), which is one of the key parameters that can represent the wireless Signal strength and the physical layer measurement requirement, is the average value of the received Signal Power on all REs (resource elements) that carry Reference signals within a certain symbol. Reference Signal Receiving Quality, RSRQ (Reference Signal Receiving Quality), represents the Receiving Quality of a Reference Signal and is mainly used as an input for handover and cell reselection decisions to rank different candidate cells according to the Signal Quality. The Signal to Interference plus Noise Ratio SINR (Signal to Interference plus Noise Ratio), which is the Ratio of the strength of a received useful Signal to the strength of a received Interference Signal (Noise and Interference), can be simply understood as "Signal to Noise Ratio".
After the wireless measurement indexes of the candidate cells corresponding to each candidate parent node are obtained through measurement, the backhaul level of the corresponding candidate parent node needs to be considered on the wireless measurement indexes of each candidate cell, so as to determine the target cell. When determining the target cell, the following rules are followed: in the case of close signal strength, in order to optimize the overhead of the IAB network, the IAB node with less backhaul level should be preferentially selected as the parent node. Therefore, in this embodiment, after obtaining the wireless measurement index of each candidate cell, the backhaul levels of the parent nodes corresponding to the candidate cells may be fused on the basis of the wireless measurement index, so as to generate a target wireless measurement index of each candidate cell, and the target wireless measurement index is used to select the target cell.
On the basis of the above embodiment, the step 103 of generating a target wireless measurement indicator for each candidate cell according to the wireless measurement indicator for each candidate cell and the backhaul level of each candidate parent node includes:
1031, for the candidate cell corresponding to each candidate parent node, updating the wireless measurement index of the corresponding candidate cell by using the backhaul level of each candidate parent node to obtain a target wireless measurement index of the candidate cell corresponding to each candidate parent node.
In one embodiment, when the target wireless measurement index of each candidate cell is generated according to the wireless measurement index of each candidate cell and the backhaul level of each candidate parent node, the backhaul level of each candidate parent node may be used to update the wireless measurement index of the corresponding candidate cell, so as to obtain the target measurement index of each candidate cell. For example, the value of the wireless measurement indicator corresponding to the candidate cell may be adjusted according to the backhaul level of the parent node, and when the backhaul level is higher, the value of the wireless measurement indicator is decreased more; the value of the wireless measurement indicator decreases less when the backhaul level is lower, so that subsequently IAB nodes with less backhaul level can be preferentially selected as parent nodes when the signal strength is equal.
On the basis of the above embodiment, updating the wireless measurement index of the corresponding candidate cell by using the backhaul level of each candidate parent node to obtain the target wireless measurement index of the candidate cell corresponding to each candidate parent node, including:
and subtracting the product of the backhaul level of the corresponding candidate father node multiplied by the weight from the wireless measurement index of each candidate cell to obtain the target wireless measurement index of each candidate cell.
In one embodiment, when updating the wireless measurement indicator of each candidate cell, the wireless measurement indicator of each candidate cell may be subtracted by a product obtained by multiplying a backhaul level of a candidate parent node corresponding to the candidate cell by a weight, so as to obtain a target wireless measurement indicator of each candidate cell, where the specific formula is as follows:
wherein, the first and the second end of the pipe are connected with each other,
a target wireless measurement indicator for the candidate cell, including any one of reference signal received energy RSRP, reference signal received quality RSRQ and signal to interference and noise ratio SINR,
is the backhaul level of the candidate parent node corresponding to the candidate cell,
a weighting factor that is a positive value is,
the value of (c) can be set in advance by the user,
according to the formula, the wireless measurement index of the candidate cell is weakened due to the increase of the return level of the father node, and the wireless measurement index and the return level can be fused into the target wireless measurement index through the formula
. In the process of screening the target cell, the target wireless signal index can be utilized
Replace wireless measurement indicators
A comparison between the respective candidate cells is made. For example, for a candidate cell of a candidate parent node of a high backhaul level, it is likely that the wireless signal detected by the IAB-MT of the IAB child node is stronger and more stable, while for a candidate cell of a candidate parent node of a low backhaul level, the signal strength is lower although the wireless signal can be detected by the IAB-MT of the IAB child node. Target wireless measurement index of the two
When comparing, the candidate cell of the parent node of the high backhaul level may also be selected as the target cell.
And step 104, determining a target cell according to the target wireless measurement index of each candidate cell, and accessing the target cell.
And finally, each mobile deployment type IAB node can determine the target cell according to the target wireless measurement index of the corresponding candidate cell. For example, each mobile deployment type IAB node sorts the target wireless measurement indexes of the corresponding candidate cells according to the magnitude of the values, selects the target wireless measurement index with the largest value from the sorted target wireless measurement indexes, and takes the candidate cell corresponding to the target wireless measurement index as an accessed target cell, and then the target cell can be accessed. When an IAB node of a mobile deployment type accesses a target cell, information including the target cell needs to be sent to a host base station, after receiving the information, the host base station determines a target parent node corresponding to the target cell, and notifies the target parent node to allocate part of resources for the access of the IAB node to be accessed. After the IAB node accesses the target cell, the host base station notifies the parent node that the IAB node originally accesses to perform resource recovery.
As described above, embodiments of the present invention provide a node access method, where for an IAB node whose mobility attribute is a mobile deployment type, the wireless measurement index of each candidate cell can be measured, and the wireless measurement index of each candidate cell is updated according to a backhaul level of each candidate parent node to obtain a target wireless measurement index of each candidate cell, and a target cell is selected from the candidate cells according to the target wireless measurement index for access. After the IAB node of the mobile attribute type in the embodiment of the present invention is started, the IAB node can determine that the target cell with better signal strength is accessed, thereby ensuring the stability of data transmission and solving the technical problem that the stability of data transmission cannot be ensured when the mobile IAB node exists in the IAB network in the prior art.
As shown in fig. 5, fig. 5 is another node access method provided in this embodiment of the present invention, where the node access method provided in this embodiment is applicable to a donor base station in an IAB network, and includes:
In this embodiment, after the IAB node is started and then accesses the cell or switches the accessed cell, if the IAB node moves, the donor base station may also reallocate a new cell for the moving IAB node to access. Specifically, in the process of starting the F1AP interface between the IAB-node-CU of the host base station and the IAB-DU of the IAB node, the IAB-DUU of the IAB node reports the mobility information to the IAB-node-CU, so that the IAB-node-CU can grasp the mobility attributes of each IAB node, and the mobility information includes information on whether the IAB node is in a mobile deployment type. And the IAB-donor-CU determines whether the accessed IAB node is a target IAB node of the mobile deployment type according to the mobile attribute of the IAB node. If so, a method similar to the UE radio measurement is adopted to send the first radio measurement configuration information to the target IAB node, where the first radio measurement configuration information is used to configure the target IAB node to perform radio measurement, and the process is shown in fig. 6.
Step 202, receiving a first wireless measurement report sent by the target IAB node, and when determining that the signal strength of the currently accessed cell of the target IAB node is reduced according to the first wireless measurement report, sending second wireless measurement configuration information to the target IAB node, where the first wireless measurement report is obtained by the target IAB node performing wireless measurement on the currently accessed cell according to the first wireless measurement configuration information.
After receiving the first wireless measurement configuration information sent by the IAB-donor-CU, the target IAB node can perform wireless measurement configuration according to the first wireless measurement configuration information, and can perform wireless measurement on the currently accessed cell after the configuration is completed, so as to obtain a wireless measurement index of the currently accessed cell. When the target IAB node detects that the signal intensity of the currently accessed cell is reduced according to the wireless measurement indexes, a first wireless measurement report of the current cell is generated, and the first wireless measurement report is sent to the IAB-donor-CU of the host base station to play a role in alarming. After receiving the first wireless measurement report, the IAB-donor-CU may determine, according to the first wireless measurement report, that the signal strength of the cell to which the target IAB node is currently accessed is decreased, and at this time, it is necessary to detect a new cell to access to continue the backhaul link, thereby ensuring the continuation of the service. Therefore, the IAB-donor-CU needs the second radio measurement configuration information sent to the target IAB node, so that the target IAB node can detect the signal strength of the candidate cell according to the second radio measurement configuration information, which is illustrated in fig. 7.
After receiving the second wireless measurement configuration information, the target IAB node may perform wireless measurement configuration according to the second wireless measurement configuration information, and perform wireless measurement on the candidate cell corresponding to each candidate parent node after the configuration is completed, so as to obtain a wireless measurement index of each candidate cell, where the specific process may refer to the specific process of obtaining the wireless measurement index of each candidate cell in step 102, and is not described in detail in this embodiment. And then, the target IAB node can generate a second wireless measurement report according to the wireless measurement index of each candidate cell and send the second wireless measurement report to the IAB-donor-CU. And after receiving the second wireless measurement report, the IAB-donor-CU extracts the wireless measurement index of each candidate cell from the second wireless measurement report, updates the wireless measurement index of each candidate cell according to the return hierarchy of the candidate father node corresponding to each candidate cell, and determines a target handover cell according to the updated wireless measurement index.
On the basis of the foregoing embodiment, in step 203, determining a target handover cell according to the wireless measurement indicator of each candidate cell and the backhaul level of the candidate parent node corresponding to each candidate cell includes:
step 2031, subtracting the product of the backhaul level of the corresponding candidate parent node multiplied by the weight from the wireless measurement index of each candidate cell to obtain the target wireless measurement index of each candidate cell.
When updating the wireless measurement index of each candidate cell, the IAB-donor-CU may subtract the product of the backhaul level of the candidate parent node corresponding to the candidate cell multiplied by the weight from the wireless measurement index of each candidate cell, so as to obtain the target wireless measurement index of each candidate cell, where the specific formula is as follows:
wherein the content of the first and second substances,
a target wireless measurement indicator for the candidate cell, including any one of reference signal received energy RSRP, reference signal received quality RSRQ and signal to interference and noise ratio SINR,
a backhaul level of a candidate parent node corresponding to the candidate cell,
a positive weighting factor.
And step 2032, sequencing the target wireless measurement indexes, and determining a target switching cell according to the sequencing result.
Then, the IAB-donor-CU sorts the target wireless measurement indexes of the corresponding candidate cells according to the magnitudes of the values, selects the target wireless measurement index with the largest value from the sorted target wireless measurement indexes, and uses the candidate cell corresponding to the target wireless measurement index as the accessed target handover cell, where the process is shown in fig. 8.
And step 204, generating cell switching information according to the target switching cell, and sending the cell switching information to the target IAB node so that the target IAB node is accessed to the target switching cell according to the cell switching information.
And finally, the IAB-donor-CU generates cell switching information according to the target switching cell, wherein the cell switching information comprises information such as the identification of the target switching cell. And then the IAB-donor-CU sends cell switching information to the target IAB node, and the target IAB node can determine a target switching cell according to the identification of the target switching cell in the cell switching information after receiving the cell switching information, and then performs the cell switching process together with the host base station, so as to access the target switching cell.
In the above, in the embodiment of the present invention, the host base station may monitor the signal strength of the cell currently accessed by the target IAB node according to the first wireless measurement index sent by the target IAB node, and when the signal strength of the cell is weak, the host base station may send the second wireless measurement configuration information to the target IAB node, so that the target IAB node performs wireless measurement on the candidate cell to obtain the wireless measurement index of the candidate cell. And then the host base station can determine the optimal target switching cell according to the wireless measurement indexes of each candidate cell and the corresponding backhaul level of the father node, so that the target IAB node is accessed to the target switching cell. When the target IAB node of the mobile deployment type moves, the host base station can determine the target switching cell with better signal strength in the moving process of the target IAB node, so that the target IAB node can switch the currently accessed cell into the target switching cell when moving. Therefore, the stability of the return link can be kept even in the moving process of the IAB node, and the technical problem that the stability of data transmission cannot be ensured in the moving process of the IAB node in the prior art is solved.
